Title A simple network nodes of the integrated design and experiment
Abstract The wireless sensor node is the basis hardware platform for establishing a Sensor Network.It’S a micro embedded—system with functions such as signal acquisition,data processing,and wireless communication.As sensor networks are usually deployed in nature environment,wireless nodes have to be low power consumption,small size and low cost,compared to the general embedded devices.Design and implement of wireless nodes,not only to provide laboratory researchers major in wireless sensor networks the related hardware test platform,can also be applied to specific projects in reality.This paper expounds the characteristics and basic principles of sensor nodes, and gives a simple wireless sensor network node integration design, including each module design is required for sensor node. Finally through the test of this thesis gives the result of experiment data network communication and sensor we system.
